They can be, but the majority are made from Crude oil. It is probably better to say that Petrochemicals are made from fossil fuels which cover both.
both have pros and cons Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their man-made counterparts Natural fibers include those produced by plants, animals, and geological processes. They are biodegradable over time. Synthetic or man-made fibers generally come from synthetic materials such as petrochemicals.
Petrochemicals
"Regenerated" in textiles refers to fibers that are made from recycled materials such as wood pulp, cotton waste, or petrochemicals. These fibers go through a process to break them down into a new form that can be spun into yarn and used to make new fabrics. Regenerated fibers are considered more sustainable than traditional fibers because they reduce the need for extracting new raw materials.
